Completed this series via bicycle with Amazing Race Bike Winners - Team 15 (aka Uncle Sam and the Firecrackers: Jvechinski, ThePharmGirl, BQueen, and STEMmom). We tackled this back on July 4th with temps around 100 degrees. This one made us so mad. We found it quickly... TOO quickly apparently. I never even touched it. I just kept yelling from my cozy bike seat, "Are you SURE there was nothing to sign?!" We found out later there WAS. Ugh. Wish I had gone down there myself. Oh well. Live and Learn. Now to bike to the final!!
